REGULATOR FOR GAS-BURNERS.

SPECIFICATION forming part of Letters Patent No, 369,960, datedSeptember 13, 1887.

To all whom it may concern.-

Be it known that I, HANNIBAL W. RAP- PLEYE, a citizen of the UnitedStates, and a resident of Philadelphia, Pennsylvania, have inventedcertain Improvements in Regulators for Gas-Burners, of which thefollowing is a specification.

The object of my invention is to so construct an automaticpressure-regulator for gasburners and like purposes as to facilitate thefitting together of the parts, to provide for readily governing theaction of the device, and to restrict the opening movement of the valve.This object I attain in the manner which I will now proceed to describe,reference being had to the accompanying drawings, in which Figure 1 is aperspective view of a pressureregulator constructed in accordance withmy invention. Fig. 2 is an enlarged sectional view of the same, and Fig.3 is a perspective view of part of the device.

The frame of the regulator consists of an upper inlet branch, A, a loweroutlet branch, B, and two hollow arms, a and b, the whole forming anopen frame, in which is contained the casing of the regulator, thelatter comprising a lower shell, d, and an upper shell, d, between whichis confined a diaphragm,f, preferably of cloth so prepared as to beimpervious to gas and proof against deteriora tion thereby, although adiaphragm of metal or other available material may be used instead ofthecloth, ifdesired. The lower shell of the regulator-easing has a hollowprojection, g, seated in a socket, g, on the outer frame, suitablepacking being interposed to prevent leakage at this point, and the uppershell has a threaded stem, 71 to which is adapted a nut, it, having aconical upper end seated in a socket in the upper portion of the outerframe, so that by turning said nut the casing of the regulator may beelevated or depressed, it be ing understood that the casing is not freeto turn. By reason of the conical end of the nut bearing at the point onthe frame, friction is reduced, and the nut is permitted to swing tosome extent laterally to accommodate itself to any want of truth in thealignment of the regulator-casing. The inlet branch A of the framecommunicates, through a passage, a, in the arm a of said frame, with thechamber begas in its flow passing through an opening, 2', to which isadapted a conical valve, m, having a stem, m, connected to the diaphragmf. The arm I) of the frame has a passage, b, which communicates with thedischarge branch 13 of the frame, and across the upper end of saidpassage extends a tubular plug, D, the bore a of which communicates withthe chamber beneath the diaphragm f of the regulator, and also throughports a with the passage b in the arm 12 of the frame.

The plug D is threaded externally for adaptation to threaded openings inthe arm I), and said plug should be notched, squared, or otherwiseconstructed at the outer end for the reception of a suitable implementwhereby it may be turned, the inner end of the plug being reduced indiameter and fitted to a bushing, p, which is adapted to an opening inthe lower shell, (Z, of the regulator-casing, suitable packing beingused between the bushing and shell and between the bushing and plug, ifdesired.

Above the diaphragmf of the regulator is a cup or receptacle, 8, which,in the present instance, is confined to the diaphragm by a thumb-nut, 8,adapted to the threaded upper end of the valve-stem m, the latter havingbeneath the diaphragm a flange or collar, 2).

Theeup 8 contains a number of pellets of lead or other suitable weights,whereby the action of the regulator is governed, the weighting ofthe cupbeing dependent upon the pressure desired at the burner or other outlet.\Vhen this pressure is normal, the valve m oeeupies such a position asto permit a fiow of gas sufficient to maintain the proper supply; butshould the demand be such as to decrease the pressure at the outlet theweight above the diaphragm fovercomes the pressure be neath the same,and said diaphragm is depressed so as to open the valve to a greaterextent and permit a freer flow of gas to restore the normal pressure atthe outlet, while if, on the other hand, the pressure at the outletexeeeds thenormal pressure, the diaphragm fwill be raised and the valveor caused to re strict the flow of gas to the lower chamber of theregulator, so as to properly reduce the pressure at the outlet.

The upper shell, d, of the regulator casing neath the diaphragm f of theregulator, the

has an opening, 2, to provide for theintroduction of the weights intothe receptacle sin setting the regulator, and so as to permit a freeflow of air into and from the space above the diaphragm f as the latter.falls and rises. In order to prevent such a drop of the valve m as wouldcause the straining of the diaphragmf when gasis cut ofi' from theregulator-chamber or the pressure therein is very much reduced, I placebeneath said valve a transverse stem, w, a portion, 10, of which isrecessed or made eccentric, as shown, so that by partially turning thestem the downward movement of the valve may be restricted to any desiredextent.

It will be evident that by the use of the nut h and plug D the parts canbe readily fitted together or taken apart, and the ready inspection ofany part of the regulator is permitted.

A laterally-projecting neck secured to the regulator-casing and adaptedto but removable from an opening in the discharge-arm of the frame may,if desired, replace the movable plug; but the use of the latter ispreferred.

I claim as my invention- 1. The combination of the outer frame, havinghollow arms forming gas-passages, with the regulator casing detachablefrom said frame, and having a valved opening, through which itcommunicates with the inlet-passage, and a laterally-projecting hollowneck fitted to but removable from an opening in the discharge-p'assagaall substantially as specified.

2. The combination of the outer frame, having hollow arms forminggas-passages, with the regulator-casing-seated upon said frame at oneend, and having at the other end a conical nut, the point of which bearsupon the frame, all substantially as specified.

3. The combination of the outer frame, having arms forming gas-passages,the regulator- H. W. RAPPLEYE.
